Well Hans was right. Who would have guessed?
After resoldering and retesting everything and chasing the schematic backwards from the left encoder, i encountered two faults.
#1 The bottom left pin of the left encoder grounded out when connected to the controls board.
#2 the bottom right pin of the left encoder had no continuity what so ever to the 2nd from the bottom right pin of the 2x4 header.
#1 solution was to disconnect the bottom left pin of the left encoder bypassing the contact on the controls board, then installing a jumper to the the bottom right pin on the 2x4 header.
Solution #2 was creating a jumper from the bottom right pin of the left encoder to the 2nd from bottom right pin on the 2x4 header, the encoder pin remains connected to the controls board because it was not grounded out.
This in effect created new traces that i probably destroyed by being too rough when clipping off the excess length of the header pins. Its a mess, but it works great.
Nino, i wonder if you damaged your controls board as well?
My continuity varied enough to convince me everything was ok. The connections were intermittent, very tricky. Only using the schematic was i able to find the faults.
Thank you for all the help everyone. Becareful clipping those thick pins! I recall Hans making a point of this this in his tips video. I still screwed it up! She's not pretty, but she works.!
